Lake Profiling: Carleton College

A National Science Foundation Grant was used to set up a lake profiling buoy on Upper Lyman Lake. The new buoy logs temperature data at four depths every 15 minutes. Once per hour, the data is transmitted by radio frequency to the geology lab in Mudd Hall. The temperature profile data is posted to a website for student and professor access.

Profiling System Description

NexSens Technology configured a data logging and radio telemetry water quality buoy system to record and transmit lake temperature profiles continuously. The NexSens water quality buoy is small and rugged. It is ideal for water quality and temperature studies on inland reservoirs. Real-time data options include cellular and radio telemetry. An onboard solar panel charges the data logger battery for continuous, unattended monitoring applications. This field-hardened buoy provides a secure platform for open water deployments.

A NexSens 4100-iSIC radio data logger transmits data from the lake site into the geology laboratory at hourly intervals. iChart software processes the data and posts it to a web-based data center (WQData), where both historic and real-time data can be viewed using a standard internet browser. The NexSens system enables Carleton geology students and professors to monitor Upper Lyman Lake at all times and easily share this information over the web.
